Update snowflake-python-connector dependency to address security risk

[BarSimovich]

PyAirbyte currently has a dependency on snowflake-python-connector==3.6.0, which in turn depends on an outdated version of the cryptography library (<4.2). This outdated version poses a security risk.

To mitigate this risk, it's recommended to update the snowflake-python-connector dependency to a version that uses a more recent cryptography version (>=4.2).

Please consider updating the dependency to ensure a secure environment for PyAirbyte users.
